PATENT OFFICE "U'IMPROVEMENT IN C AR-fl'RUQK-SHIFTING APPARATUS-v Specification forming part of L etters Paten t No. 178,079, dated May 30, 1876; applicationiiled p i February 14, 1876. p 3 i To all'whom it mag concern I Be it known that I, ROBERT HENRY RAM- SEY, of Oobourg, in the county of Northumberland, in the Province of Ontario and Dominion ot'Oanad a, have invented anew and Improved (Jar-Tr ick-Shifting Apparatus, of which the following is a specification:

-My invention consists of a couple of trucks on each side of the truck on which is the car whose trucks are to be shifted, carryinga beam extending across from one to the other under the car-body at each end, in combinationivith a depressed portion of themain truck, down which the trucks to be removed run, and detach from the car, which runs on the beam carried by the side trucks, which run atthe same time on level tracks. The tracks to, he connected-are run up the grade, and thus brought into connection with the car.

Figure 1 is a longitudinal section of the depressed railway and beams, and side elevationof the trucks, showing my improved shifting contrivanoe, thesection being taken on the line .10 d; of Fig. 2 and Fig. 2 is a transverse section taken on the line y y of Fig. l.-

Similar letters of reference indicate corresponding parts.

A represents level outside tracks along the depressed main track B. C is the car-body from-which the trucks Dare to be taken. E

are the trucks on the outside track, and F the beams for carrying the car-body on them'. By

running trucks-D into theidepressed part B a of the main track they descend so as to clear t the king-boltG, and thus disconnect from the car, and to connect other trucks they are moved up out of the depressed mart along with the car 0, so that the kin g-bolt will enter thehole for it in the bolster ofthe truck.

Tracks of different gages will be laid in the depressed Way for changing the trucks for roads of difierent gages. I

The main track may be level, and the side tracks A may be elevatedand operate in the same manner; but I prefer the arrangement shown, because itis easier to move the car along the level road and the trucks up the v inclines than to move the car over the elevations.

For shifting trucks of different gages the "apparatus will be found .very .eflicient and
